--- Fixed Bugs and Malfunctions ---
OTP-14548 Application(s): erts
Related Id(s): ERL-468, OTP-11997
A timer internal bit-field used for storing scheduler
id was too small. As a result, VM internal timer data
structures could become inconsistent when using 1024
schedulers on the system. Note that systems with less
than 1024 schedulers are not effected by this bug.
This bug was introduced in ERTS version 7.0 (OTP 18.0).
OTP-14554 Application(s): erts
Related Id(s): ERL-468, OTP-14356
Automatic cleanup of a BIF timer, when the owner
process terminated, could race with the timeout of the
timer. This could cause the VM internal data structures
to become inconsistent which very likely caused a VM
crash.
This bug was introduced in ERTS version 9.0 (OTP 20.0).
Full runtime dependencies of erts-9.0.4: kernel-5.0, sasl-3.0.1,
stdlib-3.0
